In order to form a and to improve the appearance after being attached to the door body 3, the thickness must be set relatively thick. However, since the core material 9 is formed of a metal plate, the plate thickness cannot be set to a large value due to the difficulty of its forming process, and the thickness is set to be as thin as possible. Therefore, the thickness of the rubber material 10 itself, which is put on the outer peripheral portion of the core material 9, is set to be large, and the surface area thereof is also set to be relatively large.

5, the core member 24 is integrally formed of a hollow synthetic resin material by a so-called hollow injection molding method. That is, as shown in FIGS. 2 and 3, the core 24 is made of a hard synthetic resin material, and a plurality of bolt holes 26a are formed in a triangular plate-shaped central portion 26 to which the door mirror is fixed. Along with the outer peripheral portion 27 at the center thereof
Is formed in a predetermined thickness shape having a hollow portion 24a having a substantially rectangular cross section inside. A pair of ribs 28, 28 are integrally provided side by side in the rearward direction of the vehicle body at the rear edge of the outer peripheral portion 27 on the window glass 6 side.
Through holes 28a are formed at predetermined positions 8 and 28 for holding the molten rubber therein. On the other hand, at the front end edge of the outer peripheral portion 27, three ribs 29, 29, 29 are integrally arranged side by side in the front direction of the vehicle body.
Through-holes 29a ... Injecting and holding the molten rubber inside are formed at predetermined positions of 29, respectively.

通孔３６が形成されている。As shown in FIG. 4, the bracket portion 23 is integrally formed of a hard synthetic resin material by extending the core material 24, and has a plate-shaped central portion 31 and an outer peripheral portion 32. The portion 31 has an inverted triangular opening 33 formed in the center thereof, while the outer peripheral portion 32 has a hollow portion 32a continuous with the hollow portion 24a of the core member 24 therein and a pair of upper end portions. The bolt insertion holes 34, 34 are formed so as to penetrate therethrough. Further, metal rings 35, 35 that enhance the tightening rigidity are integrally fixed to the inner peripheral edges of the bolt insertion holes 34, 34. Further, a bolt insertion hole 36 is also formed in the lower end portion.

る成形作業が完了する。The corner piece 21 is formed by the hollow injection molding method as described above, and usually, after the plasticized molten resin is filled in the cavity in the mold, gas is independently injected from the same inlet. Then, the core material 24 and the bracket portion 23 are integrally molded by injecting a molten resin to fill the inside of the cavity, if necessary. After that, the resin molded body is positioned and fixed in another mold, and the rubber material 25 is vulcanized and molded on the outer peripheral portion 27 of the core material 24. This completes the main forming operation of the corner piece 21.

ことが可能となり、コーナーピース２１の製造作業能率
の向上とコストの低廉化が図れる。As described above, in this embodiment, since the core material 24 is formed of a hard synthetic resin material instead of a metal material as in the conventional case, the degree of freedom of the shape is greatly improved and the weight is reduced. However, the thickness and surface area can be set large. Therefore, it is possible to reduce the amount of the rubber material 25 to be attached to the outer peripheral portion 27 of the core material 24, that is, the usage amount, as much as possible.
As a result, the vulcanization molding time of the rubber material 25 can be shortened, and the manufacturing work efficiency of the corner piece 21 can be improved and the cost can be reduced.

ピース２１全体の軽量化が助長される。Further, by reducing the amount of the rubber material 25 used, so-called sink marks are prevented from being generated at the time of molding, and the core material 24 is made of a synthetic resin material and the insides of the outer peripheral portion 27 and the outer peripheral portion 32 are hollow. Together with this, the weight reduction of the entire corner piece 21 is promoted.
【００１９】更に、芯材２４の合成樹脂化により発錆が

と製造コストの低廉化が図れる。As is apparent from the above description, according to the corner piece structure for an automobile door according to the present invention, the core material is formed of a synthetic resin material, so that the shape of the core material can be reduced while reducing the weight. The degree of freedom is improved, and the thickness and surface area can be increased. Therefore, it is possible to reduce the amount of the rubber material used as much as possible, thereby shortening the vulcanization molding time. As a result, the manufacturing work efficiency can be improved and the manufacturing cost can be reduced.
